INKSTAND.

To all 'zo/mm t may concern.'

Be it known that l, EMRY DAvis, a citizen' enable those skilled4 in tlie art to which it appertaiiis `to make and use the same.

This invention Vrelates to inlrstands, and particularly to in stands of the vertically movable plunger float class, such as that described and claimed in U. Si. Letters Patent granted to me June 7, 1898, No. 605,177, and the object of this invention is to improve an inlistand of this class and to make the same more efficient and practical in use.

The invention is fully disclosed in the following speciiication of which the accompanying drawing forms a part, 'in which the separate parts of my improvement are designated by suitable reference characters iii each of the views, and in which Figure 1 is a'central vertical section of my improved iiilistand and showing the same provided with a' detachable cover; Fig. 2 a view similar to Fig. l, but with the cover removed and showing the ink in the stand and the operation of the plunger iioat when the ink is poured into the stand; Fig. 3 a view similar to Fig. l, but showing the movement of the plunger float in the operation of inkiiig a pen and showing valso a` modification in the form of the top of the inkstaiid; and Fig. t a perspective view of a part of the construction shown in Figs. 1 to 8 inclusive, detached.

in the practice of my invention 'provide an inkstand comprising a main well, or receiver portion a. and a vertically movable plunger float Z) mounted therein, and in the form of construction shown, the main receiver or well a. is provided with a removable cap or closure device c.

The main receiver or well a comprises an upright body portion c2 having a base a3 and a funnel-shaped or cup-sliaped top a4, and the body port-ion 0,2 is provided with a central vertical cylindrical chamber c5 the bottom of which is closed but the top of which opens into the funnel-shaped or cupshaped top a4.

rl`he body portion of the float Z9 is exactly cylindrical in form and the outer diameter thereof is approximately the same as the diameter of the chamber a5, but said float is Specification of Letters Patent.

freely movable vertically in said chamber. .The float Zi'is also tubular in form and provided with a funnel-shaped or cup-shaped top b2 having a central tube b3 which eX- tends downwardly to or approximately to `,the bottom of the side walls of said float 'and forms, therein, an annular air chamber b4. The tube b3 is open at the bottom or provided with a vertically arranged port or passage 6G, and said tube is provided in Vthe bottom thereof with a radial recess 67, 'in the form of construction shown in Fig. 1, lto permit ink poured into the top of the tube b3 to pass out into the chamber b4. The

funnel or cup-sliaped top at of the body a2 o f the receiver is provided, in the construction shown in Figs. 1 and 2, with a rim por- -tion as threaded, as shown at a7, and the cap, or closure device c is provided with a rim c2 having a corresponding thread c3 land said cap, or closure device is also provided with a gasket 04.

In the use of this inkstand, ink is poured into the top of the plunger float ZJ and flows down through the tube b3 and out into the chamberjb as shown at ci in Fig. 2, and

this operation continues until the plunger float b rises into the position shown in said 'figure in which the funnel or cup-shaped top e4 vof the body a2 of the receiver or well and the funnel or cup-shaped top b2 of the plunger form a complete cup, and when the plunger reaches this position the pouring in of the ink is stopped .and the device is ready for use.

ln the operation of inking a pen, the pen iis'inserted into the top of the plunger float,

as Shown at e in F ig. 3, and said plunger float is depressed and the ink which cannot rise in the chamber b4 rises in the tube b3 and into the cup-sliaped top of the plun- :ger float, as clearly shown in said figure,

and when the pen is removed the plunge-r -float again rises into the position ,shown in ger a baffle device g consisting of a short tube g2 having` a raised yoke-shaped member g3 provided with a transverse recess or aperture g4 which communicates with the central bottom of the short tube g2. This baffle device is made so as to closely it the tube b3, and so that it may be adjusted therein to any desired extent or into any preferred position, and in addition to operating to prevent the too free rush of ink upwardly through said tube and out from the top thereof, as hereinbefore described, it will also serve to limit the extent to which the pen is inserted into said tube. in the upward movement of the ink through the baille device g, the said ink passes first through the tube g2 and then strikes the yoke-shaped top g3 and is deflected later# ally against the sides of the tube b3, as will be readily understood, and this operation of the said baffle device will effectually prevent the upward rush of ink through the tube Z13 and the discharge thereof, as will also be readily understood, unless, the manipulation of the pen in the operation of inking the same is reckless or careless. The baffle device f/ fits tightly in the tube b3, but may be adjusted into any desired posit-ion therein by means of a wire rod or any suitable implement inserted through either end of said tube, whereby, said baffle device may be pushed or adjusted into the desired position, but, when once adjusted, the baffle device will not be moved in said tube by a pen point coming in contact therewith in the operation of inking a pen.

In the construction shown, the top of the plunger float is tapered slightly, as shown at f, so as to Vform a thin space between the same and the walls of the chamber a5, and this, in the operation of said plunger, helps to prevent the ink from drying on the top walls of the plunger and on the walls of the chamber a5 and thus interfering with the movement of the plunger, but this tapering of the top walls of the plunger Z) is not absolutely essential and said walls of the said plunger may be of the same transverse dimensions throughout its length if desired, and it will also be understood that in the operation of the plunger a thin film of ink is formed between the walls thereof and the walls of the chamber a5 and this keeps said plunger thoroughly lubricated at all times.

Vilhile I have described the preferred method of operating my improved inkstand, it will be understood that sufficient ink may be poured into the well or into the chamber a5 through the tube b3 of the plunger 7J to raise said plunger above the position shown in Fig. 2, without materially interfering with the inking of a pen which must always be inserted into the plunger, but in practice, l prefer the method of operation liereinbefore described in which only suiiicient ink is poured into the well to raise the plunger to the position shown in Fig. 2, as this facilitates the insertion of the pen and the depressing of the plunger, as shown in Fig. 3. It will also be understood that the plunger l) is removable and may be withdrawn from the body ai of the receiver or well whenever desired for cleaning or other purposes.

By using the cap or closure device c shown in Fig. l, my improved inkstand may be securely closed and may thus be carried in the pocket, a hand bag, or in any other way, but this invention is not limited to the use of said closure cap and if desired the funnel or cup-shaped top a? of the body portion of the receiver or well may be made as .shown in Fig. 3, and a slip cap or other closure device may he employed if desired, or said inkstand may be used without a cap or closure device.

In the construction shown in Fig. l, the bottom of the tube b3 of the plunger float extends a little below the bottom of the side walls of said float and said tube is provided in the bottom thereof with radial notches or recesses bl to permit the ink to flow from said tube into the chamber b", but this construction is not absolutely necessary and transverse grooves may be provided in the bottom of the chamber a5, or any suitable construction may be employed to permit the ink to flow from the tube Z13 into the chamber b4 in the operation of pouring in the ink as hereinbefore described. The extension of the tube b3 below the bottom of the outer walls of the `plunger I), as shown in Fig. l, also operates to facilitate the action of said plunger as it prevents suction at the bottom of the plunger which would operate to hold it down, but this same result may be accomplished by providing the bottom of the chamber a5 with knobs or projections a as shown in Fig. 2, and on which the lower end 110 of the tube 3 would rest when the plunger is in its lowest position, and with this form of construction, the radial notches or recesses l1? in the bottom of the tube 3 will not be necessary as the knobs or projections e on 115 the bottom of the tube b3 will hold `the plunger in the desired position and also permit the ink to flow out from the tube b3 into the chamber a5 in the operation of pouring ink into the well, as hereinbefore described.

The use of the baille device g as herein shown and described is not limited to the form of inkstand shown, and said baille device may be used in connection with inkstands of this class having a vertically mov- 125 able plunger provided with a central tube through which the ink passes when the plunger is depressed and one of which is shown and described in the patent hereinbefere referred to, and my invention is also 180 not limited to the exact form of the float shown and describedherein and the bottom of which is open.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is l. An inkstand comprising a main well or receiver portion having a funnel-shaped top and a vertical cylindrical chamber into which said top opens, a vertically movable hollow cylindrical ioat placed in said chamber, said float being open at the bottom and provided with a cup-shaped to-p having a central tube which extends upwardly therethrough, and a tubular bafiie device inserted into and removable from said tube and provided centrally of the top thereof with a transverse raised member.

2. An inkstand comprising a main well or receiver portion having a funnel-shaped top 28th day of January 1913.
